Embodiment Construction

[0009] figure 1 Shown is the process flow chart of extracting phosphatidylcholine from soybean powder phospholipids. The technological process shown in it is to add fresh soybean powder phospholipids into the n-level leaching tank, and use the (n-1)-level leaching solution to extract for 0.5-3 hours at a temperature of 20-55°C, and then separate the solid and liquid. Finally, the solid enters the (n~1) stage, and is leached with the (n~2) stage leach solution under the same conditions, and so on until the first stage. The first stage is leached with a fresh mixed solvent. Its solvent is acetonitrile: lower carbon alcohol = 1: 10~10: 1 (by volume), the solid obtained after the first-stage leaching is residual phospholipids, which can be used to extract other types of phospholipids such as phosphatidylethanolamine. The extract solution of the nth stage undergoes vacuum precipitation to remove the solvent to obtain the phosphatidylcholine product. After the solvent is recovered...

Abstract

A process for extracting phosphatidylcholine from the powdered soybean phosphatide incldues multi-stage counter-current extracting with the mixed solvent of acetonitrile and low-carbon alcohol, and vacuum removing of solvent. Its advantages are high purity (more than 70%), and high output rate (more than 70%).

Description

technical field [0001] The invention belongs to the technical scope of extraction of chemical and pharmaceutical products, in particular to a method for extracting phosphatidylcholine from soybean powder phospholipids, which is used for health food, medicine and cosmetics. technical background [0002] The methods for extracting phosphatidylcholine mainly include: column chromatography, salting-out method, supercritical fluid extraction method, acetylation method, membrane separation method, solvent extraction method, etc. Column chromatography can prepare high-purity phosphatidylcholine products, but it is difficult to scale up the process, and the equipment investment is large, so it is not suitable for large-scale industrial production; the salting-out method can also prepare high-purity phosphatidylcholine products, but the process Complicated, harsh operating conditions, inorganic salts used in the process will cause environmental pollution; supercritical fluid extracti...
